The 1990s were a time of great economic growth and prosperity. Innovations in technology and decreased defense spending after the Cold War left businesses and governments with significant funding for infrastructure improvements. Investments in transportation, mining and energy production presented an opportunity for the company to grow.

During the decade, Louis Berger began to undertake a wider range of large-scale infrastructure projects. The firm provided consulting services for mass transit and subway projects in the United States, Turkey, Thailand and Hungary, and began its first Superfund project at Fort Riley, Kan. Louis Berger provided engineering and economic services for Yangshan Port in Shanghai, China, and BergerABAM, a Louis Berger affiliate, completed major port projects in the United States and Panama.
